Abstract

Synthesis of Substituted Nitro-chalcones and 3, 5-Diaryl-nitro-2-pyrazolines

Author(s): Aparna S. Dighade

Five different chalcones (Ia) to (If) were synthesized by condensing 2-hydroxy-3-nitro-5-methyl acetophenone with six different aromatic aldehydes in ethanol using NaOH. These chalcones were cyclized with 2, 4-dintrophenylhydrazine in ethanol yielding (IIa) to (IIf). The synthesized compounds were characterized by IR and NMR spectral analysis.
